My throat is itchy… Is this a sign of a cold?

Lately, I've been experiencing a scratchy, itchy throat, and I'm not sure if this is the early symptoms of a cold. I don't have a fever yet, but swallowing is a bit uncomfortable, and talking a lot seems to irritate it more. I'm wondering if it's due to dryness, or if it's a sign of a cold coming on. I'm also wondering if it's best to take medicine right away, or if I can just wait it out with warm tea or rest. If anyone has had a similar experience, please let me know how you dealt with it.
